Learning C# by Developing Games with Unity 5.x - Second Edition

Overview of this book

Unity is a cross-platform game engine that is used to develop 2D and 3D video games. Unity 5 is the latest version, released in March 2015, and adds a real-time global illumination to the games, and its powerful new features help to improve a game’s efficiency. This book will get you started with programming behaviors in C# so you can create 2D games in Unity. You will begin by installing Unity and learning about its features, followed by creating a C# script. We will then deal with topics such as unity scripting for you to understand how codes work so you can create and use C# variables and methods. Moving forward, you will find out how to create, store, and retrieve data from collection of objects. You will also develop an understanding of loops and their use, and you’ll perform object-oriented programming. This will help you to turn your idea into a ready-to-code project and set up a Unity project for production. Finally, you will discover how to create the GameManager class to manage the game play loop, generate game levels, and develop a simple UI for the game. By the end of this book, you will have mastered the art of applying C# in Unity.

Gameplay loops


Well done so far. You have added basic functionality like jumping, physics, and running to the PlayerController object. We are definitely going in the right direction here. The next important step is writing a neat GameManager class to help us control the game events like:

  • StartGame

  • GameOver

  • Restart

For basic games like Jake on the mysterious planet, it is a good practice to have one instance of the GameManager running and controlling all main events in the game. The gameplay loop is simply a journey from the gameplay start to the gameplay phase and the game over phase. Time to write some code!

Let's create a new C# script and call it GameManager, and write the following code:

As you can see, nothing is very complicated. We wrote very simple methods to help us control the main game events. This script does nothing yet; however, please add it to the Unity Scene. Create a new game object call it GameManager, and add the GameManager component to it. We will use it in the future...
